What's changed

Improvements

• Stop shipping compiled test files in the published packages. The *.test.ts sources were being emitted into dist, adding dead weight to every install and leaving modules that require("vitest") (not a dependency) inside the tarball, which tripped tooling that walks every file in a package. (#4833)
• Named side channels on a Session: durable, two-way realtime streams that outlive a single run and are shared across runs. Open a channel with sessions.open(id).channel(name) (or chat.channel(name) inside a chat.agent) to get an .in/.out pair addressed by name rather than the reserved default pair. Writing a side channel's .in does not wake or trigger a run, so a channel can carry out-of-band data (a stream of frames, a control signal) that many clients read while the agent produces it. (#4815)

ts // Inside a chat.agent: stream frames on a named channel, wakes nothing const frames = chat.channel("screenshots"); await frames.out.append(frame); frames.in.on((control) => { /* client control, no suspend */ });

Declare channel record types once with sessions.defineChannel(...) and infer them on both the producer and the consumer, including useSessionStreamChannel in React. Channels get a default retention that keeps them bounded, overridable per channel.

• Session triggerConfig.tags now accepts up to 10 tags, matching the run tag limit. Previously it was capped at 5, which for chat.agent left room for only 4 of your own tags after the automatic chat:{chatId} tag. (#4832)
